Ok, lady friend is having problems with her cavalier. I'm going to look at it this Friday evening, see what I can do. She sent me this from her and her BF:
the problem most likely can be attributed to me banging the **** out of the drum to un seize it the first time I took it off to change rear pads...since then the back trailing pad on left wheel ate completely through in 3 or 4 months. there was a brand new drum on it and the surface finish looked good. when you spin the lugs with the wheel off on the back left wheel you can see that the whole wheel bearing assembly is out of round. should compare to other side to make sure it isnt an optical elusion.
However, when you brake at high speed....massive vibrations which feel like warped rotor (and may be). but, when you apply pressure to E-brake at high speed there is no vibration this means that maybe only back right wheel is grabbing when e-brake is applied or the problem may not be in the drums at all
The shaking is felt all around and the rear left tire locks up when the brakes are applied
I'm thinking rear left brakes installed wrong, bent hub, or bad hub, but I don't think it's an air pocket in the right rear line or something hydraulic.
I have an indicator I can set up on the brake backing plate and check the hub face and hub edge run-out. What is an acceptable amount of run-out?
Hopefully it's something simple like a brake adjuster is fully extended.
